Title: Stop motion for yarn spinning device - has yarn guide with electronic sensor to detect presence of yarn
Inventor: SARTOR GIANCARLO
IPC: D01H13/16
Filed: 1977-01-06
Abstract: A stop motion for a yarn spinning machine includes yarn guides associated with each spinning station, the yarn guides being in the form of open eyelets.

Title: Continuous induction hardening and tempering of steel strip - via row of inductors and quenching sprays, esp. to mfr. saw blades
Inventor: TSCHOP HERBERT
IPC: C21D9/60
Filed: 1977-03-10
Abstract: Plant for the heat treatment of steel strip, which is driven from a feeder or uncoiler through an inductor supplied by a high-frequency (h.f.) generator to heat the strip above the Curie point. The inductor is directly followed by a quenching spray to obtain max. strip hardness. The spray is followed by a second inductor fed by an h.f. generator for tempering the strip below the Curie point; and the strip is then cooled in air, and fed to a coiling spool. After cooling to 200 degrees C subsequent to the tempering operation, a second spray may be used to cool the strip to ambient temp. The plant is esp. used for heat treating saw blade strip, in which case the second spray is followed by a third inductor and a spray for hardening the saw teeth. Used e.g. for heat treating saw blade strip at 8 metres/minute, using h.f. generators of 10-30 kW output.

Title: Liq. alkyd resin gelation reversal - by addn. of steam to the resin at elevated temp.
IPC: C08G63/48
Filed: 1977-05-26
Abstract: A liq. alkyd resin (obtd. by esterifying a polybasic acid with a polyhydric alcohol and removing formed water) undergoing gelation is treated with >=0.02, prf. 0.05-3 wt.%, based on the resin, steam per min. at 200-275 degrees C. to reverse the gelation. Resin is used in paints and varnishes for coating wood, metals, plastics and polymer-reinforced fibreglass. Properties of the obtd. resin are very similar to those of a resin obtd. without any gelation. In an example, a soya bean oil/heat-bodied soya bean oil/pentaerythritol/phthalic anhydride alkyd resin undergoing gelation at 210 degrees C is treated with low press steam at 100 degrees C, at a ratio of 0.05-0.1 wt.% per min., based on the resin, for 20-25 mins. to reverse the gelation process.

Title: Indicator showing amount of wear of brake linings - has profiled discs, rotated in response to lining adjustment, abutting against stop at wear limit
IPC: F16D65/60
Filed: 1977-06-20
Abstract: The lever (12) of an automobile brake is moved in the direction of the arrow (13) in order to apply the brake. The housing (9) contains a self-adjusting device which compensates for the wear in the brake linings. As the linings wear, the shaft, which carries the profiled disc (6), rotates in a counter-clockwise direction. With a new brake lining, the part (7) of the profile is just clear of the stop (8). As wear increases, the part (6) approaches the stop and when contact occurs it is necessary to replace the brake linings. The position of the parts (6, 7) in relation to the stop (8) gives an indication of the amount of lining wear that has taken place.

Title: Industrial cultivation of photosynthetic material by solar irradiation - with heat trap screens to supply electricity from surplus solar energy
Inventor: GUDIN CLAUDE
IPC: C12N1/12
Filed: 1977-08-08
Abstract: Process and installation are for controlled growth of a photosynthetic material in suspension in a nutritious, aq. medium in contact with CO2. The suspension is piped through alternate zones in which it is alternately exposed to and screened from high level irradiation. The screened zones are formed by interposing screen sections between the suspension and the source of radiation, i.e., usually the sun. The screen sections are made of a material which absorbs part of the radiation and recovers at least some of the absorbed energy for conversion and utilisation. In processing the suspension by passing it through a transparent pipe coil, the ratio of exposed time to screened time is pref. 1:1-1:100. In each exposed zone the duration of irradiation is pref. between 1 and 1/100 second. Used for cultivation of all known photosynthetic materials e.g., monocellular organisms contg. chloroplasts, photosynthetic bacteria, etc. In regions where solar radiation regularly achieves levels of energy well above that which can be efficiently employed in photosynthesis, the heat trap screens will provide a source of electric power.
